Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
While setting display type on roku to 720 got around the issue for me I do not consider it a fix. My tv and roku supports 4k. I think the issue here maybe when the commercial shown supports a higher resolution and hulu doesn't transfer back to the lower resolution for the show. Hence 720 being the lowest gets around since the commercial can't be higher than show. But not a solution as it then makes us watch all shows on roku in a lower resolution.
Totally agree. I don’t want to have to change it back when I watch a grown up well managed app like Apple or Netflix. I’m paying for 4K I’d like to see it. Anyway the new Hulu update seems to have fixed it .....so far. Ever since Disney took over Hulu has been glitchy as **bleep**. Hopefully things will smooth out soon. Good luck roku friends .
